Summary: TclDecrRefCount macro op order

Initial Comment:
The TclDecrRefCount macro first clears the string rep,
then the internal rep. This is

(a) different from the operation of Tcl_DecrRefCount
(TclFreeObj), that clears the internal rep first.

(b) dangerous, as some object type's internal rep might
well have a reference to its string rep.

Enclosed a patch that restores the correct order.
